Optimization of alpha-sialon microstructure by heat treatment
(Trans Tech Publications LTD, 2008)
Nd-doped alpha-SiAlON starting composition (Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38)) was prepared by gas pressure sintering at 1825 degrees C for 3 hrs. In order to explore the effect of post heat treatment on the developments ...
Structural characterisation of Er-Si-Al-O-N glasses by Raman spectroscopy
(Elsevier Sci LTD, 2007)
Er-Si-Al-O-N glasses have been prepared with cation ratio Er:Si:AI=3.45:3:2 containing various amounts of nitrogen (N=O, 5, 8, 15 and 22equiv.%). Glass properties such as microhardness, glass transition temperature and ...
Chemical durability behaviour of bulk glasses in the Er-SiAlON system: Surface characterisation by SEM
(Trans Tech Publications LTD, 2004)
Er-SiAlON glasses were produced by melting appropriate powder mixtures under nitrogen at 1715 degreesC using a cation ratio composition of Er:Si:Al = 3.45:3:2 and with varying nitrogen contents (N= 5 to 22 equivalent %). ...
Synthesis of the CeO2 based pigments by using enriched rare-earth oxides located at eskişehir kizilcaören region
(2004)
Pigments based on CeO2 structure are known to give various pink-orange and red brown colour in ceramic glazes. This type of pigments is prepared by high temperature calcination of CeO2 and Pr 6O11 with admixed rare-earth ...
Synchrotron texture analysis of thick BiFeO 3-PbTiO 3 layers synthesised by tape casting using Aurivillius and non-Aurivillius templates
(2012)
The solid solution between bismuth ferrite and lead titanate (xBiFeO 3-(1-x)PbTiO 3 or BFPT) possesses a morphotropic phase boundary (MPB) between the rhombohedral and tetragonal forms at x=0.7. It is of interest to ...
An investigation into bloating behaviour of bone China body during biscuit firing
(Trans Tech Publications LTD, 2004)
Amongst many studies on the textural, mineralogical and physical changes during biscuit firing of whiteware bodies, this paper attempts to investigate the bloating behaviour of a commercial bone china body during biscuit ...
Joining of SiAlON ceramics to pyrex glass
(Belgian Ceramic Society, 2004)
In the present study, pressureless joining of gas pressure sintered (alpha-beta)-SiAlON ceramics to pyrex glass was investigated. Preoxidized SiAlON ceramics were used to enhance wettability and provide chemical compatibility ...
Investigation of sanitaryware scrap behaviour in terracotta bodies
(Trans Tech Publications LTD, 2004)
In this paper, an investigation into a potential use of unfired body scrap from a local sanitaryware manufacturer in commercial terracotta production was presented. Experiments were achieved under laboratory conditions by ...
Applications of calcium phosphate based antibacterial ceramics on sanitary and tile wares
(Trans Tech Publications LTD, 2004)
In this study, metal cation consisting calcium phosphate based antibacterial ceramic powders were synthesized with wet chemical technique. The developed antibacterial powder was added to the glaze composition of the ceramic ...
Double layer glaze applications for the vitrifies glazes and surface properties
(Trans Tech Publications LTD, 2004)
Sanitaryware glazes are of the raw type and have zirconium silicate as an opacifier. Glaze compounds affect glaze properties such as mechanical strength, surface proper-ties etc. In this study, glazes were prepared in order ...
